Privacy Policy for MathPrep

1. Introduction

This Privacy Policy governs the manner in which MathPrep ("the Application", "we", "us", or "our", package name: com.mathprep.app) handles information when you install and use our Android mobile application.

Your privacy is paramount to us. We believe educational tools should empower learners without compromising their personal security or digital footprint.

2. Information Collection and Use

We collect ZERO personal data.

When you use MathPrep, we do not require you to create an account, register, or provide any personal details such as:

• Name, email address, phone number, or physical address.
• Location data (GPS, network location, or IP address).
• Device identifiers (IMEI, Android ID, MAC address, Advertising ID).
• Financial or payment information.
• Biometric or contact list data.

3. Permissions

MathPrep requires zero permissions to function. Specifically:

• No Internet Permission (android.permission.INTERNET): The application does not declare or use internet permissions. It cannot connect to the internet, cloud servers, or external APIs.
• No External Storage Access: The app does not access your photos, media, files, or external storage.
• No Camera or Microphone Access: The app has no access to multimedia hardware.

4. Local Data Storage

All study records, quiz results, bookmarks, practice mistake logs, and user preferences (such as dark mode and paper style) are saved strictly locally on your device using Android's private SharedPreferences sandbox.

• This data never leaves your device.
• It is not accessible to other applications or third parties.
• You can permanently delete all local data at any time by clearing the application storage via Android Settings or by uninstalling the application.

5. Third-Party Services and SDKs

MathPrep does not incorporate any third-party tracking, advertising, or analytics SDKs. Specifically:

• No advertisement networks (No AdMob, Unity Ads, etc.).
• No analytics or behavioral trackers (No Google Analytics, Firebase Analytics, Flurry, etc.).
• No social media integrations or tracking pixels.

6. Children's Privacy (COPPA & Families Policy Compliance)

MathPrep is designed for learners of all ages, including primary and secondary students, university scholars, and educators.

We strictly comply with the Children's Online Privacy Protection Act (COPPA) and the Google Play Families Policy:

• We do not knowingly collect any personally identifiable information from children under the age of 13 (or under 16 in the European Union).
• Because the app does not collect any data whatsoever, parents and guardians can be fully confident in their child's privacy and safety while using MathPrep.

7. Compliance with Global Privacy Laws (GDPR & CCPA)

Because MathPrep does not collect, process, or transmit personal data:

• GDPR (European Union): There is no processing of personal data. Users retain complete control over their locally stored study records.
• CCPA (California Consumer Privacy Act): We do not sell, rent, or disclose any personal information to third parties under any circumstances.

8. Security

Since all operations and calculations run entirely offline within the protected Android application sandbox, your practice sessions and notes are safeguarded by Android's native application sandboxing mechanisms.

9. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any modifications will be reflected on this page with a revised "Last Updated" date. Because the app operates offline, we advise reviewing this policy periodically if you update the application.
